Raltron SAW Filters for GNSS Applications Help Manufacturers Resolve Supply Chain Concerns 

by Colette Barron

Raltron, a global leader in high-performance frequency management components and wireless antenna products, announces specific SAW Filters for GNSS navigation systems that optimize performance and provide a viable second source alternative for other mainstream suppliers.

The RSF Series of SAW filters is specifically designed for GPS, GLONASS, Galileo, Compass (BeiDou), and soon NavIC systems. Developed to assist system engineers in optimizing performance in GNSS applications, the RSF SAW filters minimize insertion losses and ripple and provide superior signal attenuation outside the practical bandwidths with competitive temperature behavior. The RSF SAW filters can efficiently separate or combine signals of different frequencies, enabling the receiver to operate simultaneously with various satellite signals.

Raltron’s engineering services also help design engineers handle SAW filter integration challenges, including impedance matching, low noise, interface compatibility, and space constraints. The RSF Series SAW Filters family meets design requirements for tiny chip size packages (CSP), providing the standard industry dimensions down to 1.1 mm x 0.9 mm. 

“Our SAW filters’ compact size and ability to withstand higher power levels, combined with our ability to fine-tune them for specific customer requirements, make them ideal for use in today’s GNSS receivers and other devices,” said Sasha Wolloch, President of Raltron. “We are also developing SAW filters that operate in the L5 and S bands for the NavIC system in India.” 

Raltron IoT, commercial, and automotive-grade SAW filters help integrate GNSS applications with other devices. Customers may check prices and stock in distribution for immediate availability.
